Should the conversion from sourceType to targetType currently under consideration be selected?

Specified by:

matches in interface ConditionalConverter

Parameters:

sourceType - the type descriptor of the field we are converting from

targetType - the type descriptor of the field we are converting to

Returns:

true if conversion should be performed, false otherwise
